I am trying to do eco route (nanoroute with ecoroute = true). I can only do changes in M2 and M3 and in the vias V12, V23. I am able to limit nanoroute to only use M2 and M3 with ""setNanoRouteMode routeEcoOnlyInLayers 2:3"", but how do I allow it to use V12 without using M1?
Chris, in your flow, is nanoroute ripping up and re-routing all of the M2/M3, some (what it needs)of the M2/M3, or just adding to the current routing (new M2/M3 routing + existing M2/M3 routing). Do you need to ""fix"" the M2/M3 routing for the last choice? Can you do it this way? Any advice is appreciated... Thanks!
